List of guest stars

This is a list of guest stars who appeared on The Simpsons. Many episodes of iconic animated series The Simpsons feature celebrity guests contributing their voices to the show, whether as themselves or as fictional characters. This list does not include those celebrities whose voices have merely been impersonated. For the 20th anniversairy they made a special episode based on all the celebrities who have guest starred in The Simpsons.

There are several non-regular voices who make appearances but are credited as "also starring" and not guest voices. These voices are not mentioned here. As well, Marcia Wallace has made many de facto appearances and has always been credited as a guest star. Only the episodes in which her character Edna Krabappel plays a significant role are mentioned here. This is partially because the list becomes a lot more cluttered because she has guest starred in close to a hundred episodes, so although she is only credited a few times here, she has "guest starred" in many episodes.

NOTE: Glenn Close makes an appearance in this episode in a deleted scene that was originally intended for "Mother Simpson". So, although it was not recorded specifically for this episode, her appearance is noted here. The same is true for Phil Hartman as Lionel Hutz. Buzz Aldrin's appearance is from "Deep Space Homer" and Liz Georges is from short "Good Night".
